Evening is also the best time to exercise. At night and at night, hormones, the key substances of human metabolism, have the strongest response to physical exercise. Corticosterol related to fat metabolism and thyrotropin related to muscle repair (blood content) have risen sharply, and exercise is needed to stabilize hormones. At the same time, it is recommended not to play basketball immediately after meals, because the food has not been digested, the stomach is heavily burdened, and it is easy to get "gastroptosis", so exercise for half an hour after meals can avoid this situation.
